Specification of Letters Patent.

Patented sept. 5, i916.

Application iled August 23, 1915. Serial No. 46,994.

T 0 (M whom t may concern Be it known that we, REYNOLD JANNEY and Jol-1N J. GRAIN, citizensof the United States, residing at New York and Walling- "ford, respectively, in the counties of New r tion.

This invention relates to driving mechanism, one of the fundamental objects of the invention being to provide efficient means of the kind set forth which can be accurately and readily governedto effect changes or variations in speedof a member driven by Said mechanism maybe combined with various kinds of devices, and although it is of particular utility for actuating a member which has a back and forth movement by )vhich we mean either what is known as a reciprocation or an oscillation,lit is otherwise useful. For example, said mechanism might be employedfor moving a part in one direction or for a portion of vsuch movement, while independent means or even gravity might be utilized to effect the return moveinent of such part, or the reverse might be the case.

In the drawings accompanying and forming part ofthe present specification we have "illustrated in full one of the many .different forms of embodiment of the .invention which willbe setforth in detail in the following description. lel do not restrict ourselves to this particular showing; we can depart therefrom in several respects within the scope of the invention defined by the claims following said' description.

As we have already noted the driving mechanism is susceptible of general use. In said drawings, however, it is shown combined with a metal working machine, which although represented as a planer, need not necessarily be so as the said mechanism can reciprocate or otherwise operate the slide or equivalent carrier of some other kind of machine.

Referring to said drawings: Figure l is a top plan view partly in section of a planer provided with driving mechanism involv-A ing the invention. Fig. 2 is a longitudinal, vertical sectional view showing the reciprocatory table and part of the operating gearing. Fig. 3 is a vew of a portion of a planer and the driving mechanism,l the latter being in top plan view and the planer being partly in plan and partly in horizontal section. Fig. -l is a detail view of a part of the bed, the table thereon, the dogs, the oscillatory lever and certain other parts. Fig. 5 is a front elevation of the intermediate portion of the planer and the driving mechanism, the motor associated with the driving mechanism, being omitted. Fig. '6 is an elevationas seen from the right in Fig. 5, the upper portion and the right side of the planer being removed'. Fig. 7 is a view of the dri-ving mechanism, partly in section, the view being from the inside or opposite t0 that of Fig. 5. Fig. 8 is a top plan view of said driving mechanism, and, Fig. 9 a view of the same as seen from the right in Fig. 8, the gear casing being partly in section. Fig. 10 is a transverse section through the planer showing part of the gear mechanism for reciprocating the table thereof. Fig. 11 is a detail View in sectional elevation of the driving mechanism at the motor end thereof or what is shown as being the right end in Figs. l and 3.

Like characters refer to like parts throughout the several views, which it will be observed are on different scales.

1We have shown our driving mechanism as combined with a planer. The planer shown comprises a bed 2 having ways for supporting the work table 3 which is reciprocatory in a straight path. This table or slide 3 presents as may be inferred merely one of many kinds of members which can be advantageously operated by our driving mechanism. On the under side of the table 3 is a longitudinally extending rack 4 (Figs. 2 and 10) in mesh with the pinion 5 which in turn meshes with the spur gear 6, the shafts 7 and 8 of the respective gears 5 and 6 being suitably supported by the bed or framing 2 of the planer. The shaft 8 eX- tends outwardly beyond the bed 2 and as illustrated has fastened to its outer end,

the bevel gear 9 (Figs. 3 and l0) in mesh 11, the framing of the planer being pro'- vided with suitablev means for supporting the shaft 11 and for also incasing the gears 9 and 10.

il' e have described one convenient means by which the table 3 can be operated. 1t will be clear that when the shaft 11 is turned one way the table 3 through the intervening describ ed parts will be moved in a predetermined direction while on reverse movement of said shaft 11, opposite movement of the table will result through said intermediate parts. equivalent member is automatically oppositely rotated so as to effect reci'procations of the table 3.

re prefer to employ as part of the driving mechanism, what is known as a hydraulic variable speed gear. Such a device is shown in the drawings and generally speaking is practically a duplicate of that set forth in Letters Patent. Non 924,7 87 granted to Reynold Janney, June 15, 1909. As the invention does not reside per se in a hydraulic variable speed gear, we will not describe in detail that represented.r lt is deemed' desirable, however, to briefly set forth the vorganization of such a device which ,comprises a driving shaft or as itis some times known fi-shaft as 12, and a driven shaft, or as it is ysome times called B-shaft as 13. Although the pa/rt 12 has been considered as a driving shaft it in turn is driven by power preferably continuously, the electric motor 11 (Figs. 1 and 3) being shown for this purpose, the armature shaft of the motor being connected with the shaft 12 by gearingsu'ch as that denoted in a general way b v 15. As representedthe driven or B-shaft is connected by ailexible coupling as 17 or otherwise' with the shaft 11. .It will, therefore, be obvious that the speed of the shaft 11 and the direction o f movement thereof will conform to those of the driven or B-shaft 13. In the casing of the lhydraulic variable, speed gear is `mechanism by i which through the aid of suitable means the shaft 13 or analogous element can be driven .either forward for; backward at different o speeds'. As a part of the hydraulic variable speed gear is a controller which may take the form of a shaft, anda regulator which lnay consist of what is known as a til'tlng' box. This regulator or tilting boxhas ai neutral position,l and when occupying the same the shaft 13 will be at rest or stationary.A If said 'regulator or tilting box be moved in one direction from sa'id neutral Lposition, the shaft `13 Will be driven, for `instance forward, while if the tilting box be moved in the opposite direction from said neutral position', the shaft 13 will be turned oppositely, the velocity of' the shaft 13 de-r pending upon the position of saidtilting .G5 box. lt will be evident that as the tilting In the present case the shaft 11 orI box, merely one of several types of regulators suitable for the purpose, 'leaves its neutral position, thel speed of the shaft 13 will be progressively increased. The controller is ydenoted by 18 and is connected with the tilting box or regulator 19. The

lower end of the control shaft 18 is connectlmoved endwise, its endwise movementl depending upon the direction in which said control shaft is turned, by virtue of which said control shaft by its saidendwise movement can effect a change in position of the tilting box 19 to move it from its neutral position. in either direction as already stated. The mounting and action of the control shaft 18 are exactly like what is shown in Letters Patent 1,108,443 kissued `August 25, 1914 to Reynold Janney. ln

this particular patent is shown what is known as a follow-up motion, and this follow-up motion we use in the present case, but, however,.for a different purpose.

In conjunction with the control shaft 18 or itsequivalent we provide means for lim- 1ting the motion thereof yin opposite directions from the neutral, it being evident that the shaft is in its neutral position when the tilting box is in its neutral position. The means shown where-by this function may be secured answers satisfactorily and will now bel described. Fulcrumed at one end for instance to parallel links as 21 mounted for swinging movement upon a suitableibearing at the outer end of the hydraulic variable speedgear, isy a lever 22 (Figs. 3 to .8 inclusive). Saidlever has between its ends the loop 23 inv which' is pivoted the block 2t connected to the upper end of the control shaft 18 so that as the controlshaft 18 moves upward from its neutral position or downward therefrom, the lever 22 is respectively swung up Yand down. The extent of movement of said lever-governs the speed of the shaft 13 and through the intermediate described parts that of the table 3.' lt will, of course, be obvious that the table can be driven slowly in one direction and quickly in the other and vice versa. The governing lever 22 has at its inner end the .guide-eye 25 to receive the rod 26 equipped with 'adjustable stops 27 and 28, hereinafter more particularly described. rlhe two stops are shown'at the limits of their outer adjustments. By moving them into-ward the eye`25, the motion of the lever 2,2 will be decreased so as to correspondingly -decrease the velocity Iof the shaft The stop 27 will govern the speed of the table 3 in one direction while the stop 28v will govern the speed of the table in the opposite direction.' The stops- 27 and 28' consist of elongated sleeves slidablc on the stationary rod 26,\each being "provided with a thumbscrew 29 to hold the same in an adjusted position, the thumbscrews as will be apparent, being adapted to' engage the said rod. Each of the` stops also has a wheellike or annular manipulating portion 30 which `can be grasped tov facilitate its adjustment longitudinally of the rod. The rod is connected t0 and rises from a movably mounted member as will hereinafter appear. The lever 22 is automatically oscillated by means coperative with the table 3, owing to which said table can be .automatically reversed, and suitable meansfor this purpose will be hereinafter set forth.

Above the A-shaft 12 is an auxiliary shaft 31 (Fig. 7 for example) which is driven continuously in some suitable manner by said A-shaft, sprocket gearing denotedv in a general way by 32 being showirfor this purpose. Loose on this shaft and housed in the casing 33 are inwardly facing bevel gears 34 and 35, the clutch member 36 being coperative with the two gears 34 and 35 and being adapted to alternately frictionally clutch said gears to the continuously rotative shaft 31. This clutch member 36 is splined or feathered to the shaft 31 for rotation therewith and longitudinal movement thereof, its opposite cone ends being adaptedtoalternately engage the walls of the conical cavities 37 in the saidgears 34 and 35. In Fig. 7 lthe clutch member 36 is shown as occupying its neutral position, the same applying to the controlshaft 18 and governing lever 22,.the consequence being that the driven shaft 13 will be at rest. The

two bevel gears 34 and 35 mesh with the bevel gear 38 (Figs. 8 and 9) rigid with the bevel gear 39, the latter in turn meshing with the bevel gear 18 which is splined to the control shaft 18. It '.will, therefore, be clear that on the turning of said gear 18 said control shaft owing to its threaded connection with the gear or nut- 20 assumed to be stationary at this time, said shaftv 18 will be moved endwise, its direction of movement depending upon the direction in which said bevel gearv 18 is turned.

The clutch member 36 in the present case is movable back and forth on the auxiliary shaft 31 by `the shipper member 40 shown as being .of oscillatory form and pivoted. between its ends for swinging movement. To the lower branch ofthe shipper member 40 is jointed the rodv 41 as shown bestin Fig. 7 (see also Figs. 1, 3 and 5). This rod 41 is also jointed to the oscillatory member 42 pivoted on the framing of the planer and to which in turn the rod 43 is connected, said rod in turn having a connection with the lever 0r rocker 44 mounted on the bed 2 andshifted in alternate directions by dogs as 45 and 46. These dogs and lever 4-4 and 70 connecting rod 43 are common in planers and therefore, require no extended description, the dogs as understood to those conversant'in the art, heilig adjustable longitudinally of the bed and being adapted to alternately swing the rocker 44 in opposite directions. The lever or rocker 44 also has a handle 47 by which it can be manipulated to move it to neutral position and thus prevent its operation by said dogs as usual in the art. Vhen the rocker 47 is thus manually operated, it moves throughthe inter-4 mediate described parts the clutch member 36 to its intermediate or neutral position as shown in'Fig. 7. During planing or equiv- 85 al'ent operation, however, the rocker 44 is rocked alternately in opposite'directions b v saidV dogs. It will be assumed that the Aor primary shaft 12 is inl action and that the clutch 90 member 36 and contrblling shaft l18 and regulator 19 are in their neutral positions. In this event the shaft 13 and hence the table or carriage 3 will be at rest. To start the bed 3 the rocker or lever 44 will be manipu- 95 lated s0 as to throw through the intermediate described parts the clutch member 36 into engagement with one or the other of the bevel gears 34 and 35. 1t will be assumed that the clutch member 36.is moved into engaging relation with the bevelgear 34, and that said bevel gear is utilized to effect through the)described connections the movement of the table 3 ina forward direction. A s soonas the clutch member 36 is engaged 105 with saidv bevel gear 34, the latter will be rotated .to effect through the partsdescribed including the bevel gear 18 the elevation of the control shaft 18 and lever 22, this` motion continuing until the lever strikes the 110 upper stop 28 at which point further niov tion of the lever and control shaft will be practically arrested. As the control shaft 18 is swung upthe tilting box 19 is moved upward from its neutral position'to cause' 115 the movement of the shaft 13 at the requisite speed and said shaft 13, owing to its described connectionswith the table`3, will advance said table until the dog 45 strikes the lever 44 and swings the 'same over s the slide 120 D and therefore lever 22 are lowered until the lever strikes the stop 27, the lowering of the. shaft 18 from its upper Kextreme position to its lowery extreme position edecting a reversal of movement of ,the tilting box 19 and 130 Ydisengaged from the bevel gear 35.

therefore a reversal in motion of the shaft 13, by virtue of which return movement of the slide 3 is effected, continuing until the dog 46 strikes the lever 44 and swings said vlever over so as to cause the clutch member 36 through the described parts to again engage the gear 34 at which point the motion of thetable 3 is reversed or said table is caused to advance, these operations continuing in sequence as long as the lever 44 is positioned for alternate operation by the dogs 45 and 46.

The rod 26 is rigidly connected with and rises from the arm 64 which it Will be remembered, is connected with the shipper member 40. It will be noted that We have mentioned the fact that the motion of the lever 22 is virtually arrested in alternation by the stops 27 and 28. This lever when it strikes either stop has a slight further .movement. On this further movement it will raise the rod 26 if the stop 28 is struck, while if the lever engages the stop 27 the rod will be lowered during this final and almost imperceptible movement of the lever 22. As a matter of fact the motion of the lever is practically stopped when it strikes either of the stops. There will be a small amount of motion and this is utilized .to disengage the clutch member 36 from the gears 34 or 35 which it may engage. For instance on the final part of the 'movement of the lever 22 after the latter has struck the stop 28 the rod 26 will be raised, thus raising the arm 64 and through the shipper 40 disengaging the clutch member 36 from the bevel gear 34. On downward movement of the lever 22 the arm 64 as will be inferred, is moved downward through the action of the rod 26v so as to cause the clutch member 36 to be When the clutch member is engaged with the bevel gear which for the time being it coperates with further motion of such bevel gear and therefore of the bevel gear 38 and parts actuated by the latter will be arrested.

Fastened in some suitable manner to the driven or secondary shaft 13 from the hydraulic Avariable speed gear, is the!" pinion 50 in mesh with the spur gear 51. This spur gear 51 is fastened to the section 52 of a divided shaft, the section 53 of said divided shaft having a bevel pinion 54 (see Fig. 11) in mesh with the gear or nut 20 With Which it will be remembered the control shaft 18 has a threaded connection as shown for eX- ample in l gs. 7, 8 and 11. As Will be understood the shaft sections 52 and 53 are coaxial and to them are connected clutch members 55 and 56 of friction type, the clutch section being rotative With the shaft section 52 and the clutch Section 56 being rotative With and movable longitudinally of the shaft section 53T Surrounding the clutch section 56 is a split band 57 to Which the parallel links 58 are connected (Figs. 7 and 8), these links being connected by the pin 59 which is in turn connected with a crank arm 60 fastened to the shaft 61 mounted on the bracket 62 sustained by the hydraulic variable speed gear. To the shaft 61 is fastened a crank arm 63 to which the link 64 is pivoted, said link being jointed to the arm 64 rigid with the shipper member 40 already described, the parts being so positioned that when the clutch member 36 is moved from either direction toward its neutral position, the clutch section or member 56 will be caused to engage the clutch section or member 55 so that the tilting box or regulator 19 can be moved to its neutral position. It ivill be clear that When the shaft 13 is in motion the gears 50 and 51 will be rotated soas to rotate the shaft section 52, and if the clutch sections 55 andI 56 be not in engagement the shaft section 53 Will not be rotated. It will,therefore, be evident that when the lever 44 is manipulated tothrow it to its mid position where it can be operated by either of the dogs 45 or46, the clutch member 36 will be moved to its neutral position and at the same time through the described parts, the clutch member 56 will be caused to engage the clutch member 55, so that the shaft section 53 can in the manner already set forth be rotated to rotate the bevel pinion 54 and therefore the nut or bevel gear 20. lVhen the nut is turned the control shaft will be returned to its neutral position, and as said control shaft is returned to its neutral position, the tiltingbo'x through its connection with said control shaft is also returned to its neutral position, and `when the latter occurs rotation of the shaft 13 is stopped.

To the bevel gear 34 is connected a suitable manipulating hand Wheel 65 Which presents a convenient means for moving primarily at the will of the operator, the carriage or table 3 to a predetermined position. It will be assumed that the clutch member 36 has been moved to its neutral position and that the control shaft 18 and regulator 19 are in corresponding relations and that kit is desired to effect lmanually the adjustment of the slide or table 3. ln this event the hand Wheel 65 is turned to raise or lower through the intermediate parts the regulator 22 and thereby in the manner described effect the turning of the driven or secondary shaft 13 and therefore, the desired movement of the slide or table 3. As soon as the table or slide is in the adjusted position the regulator or tilting box 19 Will be moved to its initial or neutral position through the agency of the clutched shaft sections 52 and 53 and bevel gear 54 acting in the manner already described. It will be understood that when the hand Wheel 65 is turned to effect the movement of the tilting box 19 from the neutral there is another train of devices tending to return said tilting box to neutral and to effect the movement of the slide, carriage or table 3 to an adjusted position it will be necessary to turn the hand wheel 65 faster than the opposing parts act against the tilting box, these opposing parts presenting what is known as a follow-up motion. lVith the clutch member 36 in the neutral and the adjustment being attained through the operation of the hand wheel 65 or analogous part, the tilting box 19 is returned to its neutral position practically instantly after the hand wheel 65 is freed by the operator.

This train of devices to which we have referred is what is known in this art as a follow-up mechanism, and in the construction shown comprises the gears 50 and 51,

the shaft sections 52 and 53 (when clutched together) bevel ear 54', bevel gear or nut 20 and control shaft `18 which it will be remembered is connected with the tilting box.
